DETECTING CONDITION AND TROUBLE AREA
If the ECM detects DTC "P0100" it operates the fail safe function, keeping the ignition timing and injection volume constant and marking it possible to drive the vehicle.





HINT: After confirming DTC P0100 use the OBD II scan tool or LEXUS hand-held tester to confirm the mass airflow ratio from "CURRENT DATA".
